How do we make chains where two filters feed into one or one filter feeds two 
filters?  If you look in my sandbox we can accommodate this via:

static import a.m.util.Util. linkParentWithChild; // to be written

IoFilter foo = new FooFilter();
IoFilter link = new LinkStateFilter();
IoFilter checksum = new ChecksumFilter();
IoFilter log = new LogFilter();

link.addLinkStateListener(foo);
linkParentWithChild(foo, checksum);
linkParentWithChild(link, checksum);
linkParentWithChild(checksum, log);

acceptor.setFilters(foo);
